Who and where should i buy a new top for a 69 barracuda

I met with the top installer today and put money down so he will order the top I'm going the same as the original which looks to be the same color white as my seats. I have in the box a brand new white back glass window which i brought in to show him and he told me that it was the wrong material for my car which the color white was bright white and as far as i know it was the same color white top that was on the car when i got it. The car went through a restore back in the early nineties and had a new top put on it but it was never finished and pushed out into a open lot where it sat until i resuced it three years ago it was almost melted into the ground when i picked it up. It is a long story how i ended up with the car but in the end it has come out nice so, this spring will be the first time the car has seen the road since the early nineties. Thanks for all the input
